I've been following the progress of Runic Games' Hob. I really like the art direction and the adventure/discovery elements they've worked into a mechanical/organic world. This is an alternative bridge idea. I really liked that you literally unlock your pathway in HOB and I wanted to create a path that you unlocked/activated piece by piece that was it's own little mini landscape. I did very basic blocking in Modo to make sure my spatial understanding was in place and designed the rest in photoshop.
